Scott,

There are lots of pitch correction options out there but the 'audio to midi' capabilities is what knocked my socks off. I do not play keyboards...at all, but I do play guitar. I can take a recorded guitar track and convert it to a midi file and then add any VSTi to it.

Perhaps there are other programs that can do that but since I use Presonus Studio One v2 and it comes with Melodyne Essentials and over the summer Melodyne made an offer to Presonus S1 users to upgrade to their top program Melodyne Editor (which can do the audio to MIDI conversion) for $150...I jumped at it!

Here an example:

Since Notes is a midi power user, perhaps this is what he is excited about Then again...maybe not.
